If sleeping is harder than it should be, the Dreem band might be able to help you figure out what you're doing wrong. The Dreem band is a fabric-covered headband that wraps around your head and uses a combination of sensors like the ones in your Apple Watch to detect various biometrics like your heart rate and respiration activity. It also uses bone conduction to communicate audio cues to you privately. Item 4

Samsung's shown off its Micro LED technology in the past, using it to build The Wall, a 146-inch TV. The company's now showing off a smaller Micro LED TV. Using Samsung's Micro LED panels, you can create a variety of display sizes supporting different aspect ratios, going from an ultra-wide 21:9 screen to a perfectly square 1:1 display without losing image quality. 56.

Supermarket shelves are filled with plant-based alternatives to cow milk, including soy, nuts, and coconut milk. These products are popular with consumers who cannot drink cows' milk for health reasons, as well as with those concerned about animal welfare and environmental sustainability. While the dairy-free options work well with cereal or in coffee, they fail miserably when it comes to making milk-based products like cheese or yogurt. However, these shortcomings may soon be a thing of the past, thanks to a new company in California, which has figured out how to create animal-free milk in a laboratory!

Perumal Gandhi and Ryan Pandya founded the company in 2014 after becoming increasingly annoyed with the lack of cows' milk-free alternatives, particularly for cheese. For Gandhi, who stopped consuming animal products five years earlier due to environmental and animal welfare concerns, the motivation to create a better alternative stemmed from his love of cheesy pizza. Pandya was spurred into taking action after being forced to eat some "really bad" dairy-free cream cheese on his sandwich.

The two MIT biomedical engineering scientists decided to join forces to create a more realistic alternative to dairy-based products. In their university lab, the pair spent nine months first isolating cow DNA and then inserting it into yeast. This genetic modification enabled the yeast to produce the necessary milk proteins. The final step of the process involved mixing the proteins with some plant nutrients and fats.
